Discrete particle swarm optimization method for the large-scale discrete time–cost trade-off problem

作者：

Highlights：

• A novel PSO method is presented for the discrete time–cost trade-off problem (DTCTP).

• The proposed discrete PSO outperforms the state-of-the-art methods.

• High quality solutions are achieved within seconds for large-scale instances.

• New large scale benchmark DTCTP instances are generated and are solved to optimal.
